Information technology — Office equipment — Method for measuring digital printing productivity
ISO/IEC 24734:2009 provides a method for measuring the productivity of digital printing devices with various office applications and print job characteristics. It is applicable to digital printing devices, including single function printing and multi-function devices, regardless of print technology (e.g. inkjet, laser). Devices can be equipped with a range of paper feed and finishing options either directly connected to the computer system or via a network. It is intended to be used for black and white (B&W) as well as colour digital printing devices. It allows for the comparison of the productivity of machines operating in various available modes (simplex, duplex, size of substrates, etc.) and office applications when the test system environment, operating modes, and job mix for each machine are held identical. ISO/IEC 24734:2009 includes test files, test setup procedure, test runtime procedure, and the reporting requirements for the digital printing productivity measurements. It is not intended to be used for devices which are not able to print on a media size of A4/8.5”x11” or for devices which are not able to collate multiple copies of a print.

Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees
established by the respective organization to deal with particular fields of technical activity. ISO and IEC
technical committees collaborate in fields of mutual interest. Other international organizations, governmental
and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information
technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as
an International Standard requires approval by at least 75 % of the national bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.

ISO/IEC 24734:2009(E)
Introduction
Many digital printing devices produce printed pages at a different rate than their nominal speed when running
with different modes (simplex, duplex, print quality modes), different substrate weight, system environments,
applications and file content, and finishing options. The degree to which a reduction in productivity is
experienced depends significantly on multiple parameters of the job workflow. The most dominant of the
parameters of the job workflow are: system environment, application, and job characteristics such as the
number of pages in a set to be printed, single-sided or double-sided output pages, quality mode, number of
print sets to be produced, substrate weight/size used, and finishing options, and job content complexities such
as monochrome vs. colour, text/vector vs. raster, page scaling and colour conversion. The existing
International Standards (ISO/IEC 10561) only address printing throughput for Class 1 and Class 2 printers and
(ISO/IEC 14545) only addresses analog copier productivity, therefore both are not suitable for comparing
colour printing devices or high-speed page-oriented printing devices with many finishing options and
connectivity configurations.
This International Standard provides a general method for measuring the productivity when the above-
mentioned job workflow parameters for digital printing devices are taken into consideration. This International
Standard also includes a suite of test files, test-platform (hardware and software) setup guidelines, and a
procedure to be used for measuring digital printing productivity. It allows manufacturers and buyers of digital
printing devices to describe the productivity of various digital printing devices with respect to representative
office usage patterns.

INTERNATIONAL STANDARD ISO/IEC 24734:2009(E)
Information technology — Office equipment — Method for
measuring digital printing productivity
1 Scope
This International Standard specifies a method for measuring the productivity of digital printing devices with
various office applications and print job characteristics. This International Standard is applicable to digital
printing devices, including single-function and multi-function devices, regardless of print technology (e.g. inkjet,
laser). Devices can be equipped with a range of paper feed and finishing options either directly connected to
the computer system or via a network. It is intended to be used for black and white (B&W) as well as colour
digital printing devices. It allows for the comparison of the productivity of machines operating in various
available modes (simplex, duplex, size of substrates, etc.) and office applications when the test system
environment, operating modes, and job mix for each machine are held identical. This International Standard
includes test files, test setup procedure, test runtime procedure, and the reporting requirements for the digital
printing productivity measurements.
This International Standard is not intended to be used for devices which are not able to print on a media size
of A4/8.5”x11” or for devices, which are not able to collate multiple copies of a print.
This International Standard is not intended to replace manufacturer's rated speeds.
The productivity of a digital printing device depends on factors other than the printing device itself. These
include, but are not limited to, computer manufacturer and model, central processor type and speed, RAM and
hard disk memory capacity and speed, software driver, version of the application being used, operating
system, and the type and speed of the communication path from computer to printing device, etc. Because of
this, in order to make useful and accurate direct comparisons of printing productivity with this International
Standard, the same computer system hardware and software shall be used for measuring the printing devices
if for the purpose of being directly compared one to another. For every printing productivity measurement, the
basic specifications of the computer hardware and software shall be included with the results of the printing
productivity measurement.
NOTE Important note for the use of this International Standard. There are other factors that influence the number of
prints that a person can make on a printing device within a defined time period. These factors include typical job portfolio
that is printed on a particular printing device, reliability of the system, downtime due to a service call, ease-of-use, (un)load
paper during printing, routine maintenance, interaction with other users of the printing device and the network, etc. Such
productivity items are not taken into account within the scope or methods of this International Standard.
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1
category test
test pertaining to one of two separate categories; Office category and Advertising and Graphics category,
whereby the Office Category test is used to test and report FSOT, ESAT and EFTP using content from typical
office applications and the Advertising and Graphics Category test is used to test and report FSOT, ESAT and
EFTP using applications and files representing more complexity, higher coverage and a higher ratio of image
and graphic content such as pictures, gradients and embedded elements

ISO/IEC 24734:2009(E)
2.2
collation
printing device's ability to produce multiple hard copies of an electronic document in repeating original order,
such as 1234, 1234, 1234.etc, which may be achieved through either software features that ensure proper
output order or via a hardware finishing device
2.3
default driver
printing device driver that is automatically selected as the default per the manufacturers’ installation procedure
2.4
duplex printing
printing where the printing device can make a number of prints with the printing being done to both sides of
the sheet
NOTE Other equivalent terms are “two-sided printing” or “two-sided perfecting”.
2.5
EFTP
effective throughput
average speed at which a device produces pages measured from the initiation of the job through the complete
exit of the last page of the last test set
NOTE EFTP is expressed in images per minute (ipm). EFTP can be affected by the digital processing time of the test
set as well as the run time of the test set.
2.6
ESAT
estimated saturated throughput
rate at which a device produces pages measured from the complete exit of the last page of the first test set
through the complete exit of the last page of the last test set
NOTE ESAT is expressed in images per minute (ipm).
2.7
feature performance percentage
ratio of the printing performance (such as FSOT and ESAT) with the subject feature ON versus the printing
device default baseline performance (without the subject feature ON)
2.8
feature performance test
optional test used to evaluate productivity changes with various printing and finishing features enabled
NOTE The feature performance test suite is run with default printing system settings to establish a base line, and
then with the selected feature (e.g. stapling) ON, for comparison.

ISO/IEC 24734:2009(E)
2.12
host-based controller
〈printing devices with a host-based controller〉 page description interpreter and RIP reside in the host
computer and these processes convert the PDL into a simplified format such as a raster bitmap, and the
simplified data are then sent to the printing device
NOTE Most of the data and images processing is done on the host computer side. The performance of the printing
device depends upon the whole system — the host computer, the data transfer, and the printing device.
2.13
initial installation state
state of the test platform after the installation and configuration of the operating system and applications but
before the installation of unique software, e.g. print driver for the printing device under test
2.14
input image equivalent
number of original electronic input images printed independent of the number of hardcopy output sheets the
images are printed on
NOTE Input image equivalent is expressed in terms of the equivalent number of images input from the source test
file. For example, if two A4-sized input images from the test file are printed on one-side of an A3 page in simplex printing,
the output printed on this A3 page is 2 A4 input image equivalent. For another example, if four A4-sized input images from
the test file are printed in reduction on one-side of an A4 page in a 4-up mode in simplex printing, the output printed on this
A4 page is 4 A4 input image equivalent.
2.15
interface/network
interface between the host and the printing device, such as a direct (via parallel, serial, USB, Firewire or
wireless) or an indirect (via network router/server) connection
2.16
LSOT
last set out time
number of seconds between the initiation of the job to the complete exit of the last page of the last test set
2.17
nominal printing speed
printing rate, excluding time to first page printed, and measured when producing pages in a continuous
printing mode with a single static data page using a nominal weight substrate
NOTE Nominal printing speed is expressed in pages per minute or images per minute.
2.18
PDL
page description language
specifies commands and data structures that a printing system interprets to produce an intended print page
image
2.19
PDL-based controller
〈printing devices that include a PDL-based controller (such as a Postscript RIP)〉 host computer processes the
page information via a software application into a standardized or well-known format (with embedded PDL and
compression) and the standardized/well-known page data is sent to the printing device via an
interface/network
NOTE The printing device's controller has its own decompressor, PDL Interpreter and RIP, with job storage and the
required large amount of processing power. Most of the final page data processing, images processing, job and file
management is done on the printing device side. However, the performance of the printing device still depends upon the
whole system - the host computer, the data transfer, and the printing device.

ISO/IEC 24734:2009(E)
2.20
printing device
produces hard copy output, or prints on media such as paper, from digital electronic documents
NOTE The function of the device is not limited to printing only, such as is the case with multi-function devices, which
have the ability to print and perform other functions such as copy, scan and/or digital send.
2.21
RIP
raster image processor
component used in a printing system, which produces a bitmap
2.22
set count
the total number of sets printed during a test run, with set count N, and then N (as in N test sets) x M (number
of pages in one test file) pages will be printed.
NOTE This is often referred to as copy count in the application or print driver setting.
2.23
simplex printing
use of a printing device when only a single side of a sheet is printed on
NOTE Single-sided printing mode is similar to the copying modes often referred to as 1:1 mode, Simplex to simplex,
or single-sided originals to single-sided copies.
2.24
summary report
presentation of results including the average overall FSOT and ESAT values calculated for a given category
or feature test
2.25

productivity tests, including, but not limited to a computer installed with an operating system and applicable
application software, installed printing device software, hardware and software interfaces, and timing devices
(stopwatch or automated)
2.27
test run
refers to the operation of printing one test file, in a particular system configuration, with a particular set and
page count
NOTE Print times are recorded for each test run.

3 Test Parameters and Conditions
3.1 Test Platform
Due to the rapid change of computer technology, a common test platform (hardware and software) that can be
used for productivity testing over time is considered to be not practical. Instead, when a test platform is used,
the test platform system parameters that may affect digital printing productivity measurements (see Annex A)
shall be recorded.
3.2 Test Platform Test Setup Procedures
The test platform test setup procedure includes sections for setting up the test platform computer and the
printing device to be tested.
3.2.1 Initial Platform Setup
The test platform hardware should be installed as per the manufacturer's instructions. The test platform
hardware information shall be recorded as listed in Annex A. The test platform operating system and
applications should be installed as per the manufacturer’s instructions. The test platform operating system and
application information shall be recorded as per Annex A. All settings or selections made during installation
that differs from the application's default settings or operating system’s default settings shall be recorded.
• The test platform should be configured for the appropriate connection environment, such as direct USB
connection or network Ethernet connection, and the information shall be recorded as per Annex A along
with all settings and selections that differ from the installation default configuration.
• It should be verified that the test platform is configured for optimal performance by evaluating system
parameters such as hard disk fragmentation and compression, swap memory size, etc. Any settings,
changes or optimizations made that differ from the installation default condition shall be recorded.
• The test platform is now in the Initial Installation State. All recorded settings shall be included in the Full
Detailed Report.
3.2.2 Creation of Disk Image of Test Platform (optional)
Disk imaging software may be used to enable the system to be restored to the Initial Installation State. Create
the disk image after the test platform has been configured and before the print driver for the printing device is
installed. Record the disk imaging software used and all settings that differ from the imaging software’s
installation default condition.
3.2.3 Initial Test State
The test platform shall be restored to the Initial Installation State before beginning the sequence of tests for
each new printing device. Each printing device product bundle or printing device hardware configuration
should be considered a “new printing device”. Record the method used to establish the Initial Installation State.
3.3 Printing Device System Setup
Place the printing device on a horizontal surface and setup the printing device according to the manufacturer's
recommendation. Install the software (driver, port, etc.) recommended by the manufacturer. Use the most
recent print driver available from the manufacturer. The driver and driver version shall be specified on the test
report.
The standard test shall be conducted using the manufacturer's default driver for the given printing device. If a
default driver is not installed/selected automatically by the manufacturer's installation procedure, consult the
manufacturer's documentation and use the recommended driver. All image, print quality, mode and speed
modifiers shall be at their factory pre-set configuration for the printing device and default installed condition for
© ISO/IEC 2009 – All rights reserved 5
---------------------- Page: 11 ----------------------
ISO/IEC 24734:2009(E)
the driver. If the printing device and driver differ, then the driver defaults shall be used. Disabling manufacturer
default installed features, routines or applications, is not allowed. Examples include, but are not limited to the
following: automatic cleaning or calibration cycles, bi-directional communications and energy save settings. It
is allowable to disable automatic media detect and select plain paper.
The file shall be rendered on the page in a size corresponding to the dimensions in the test page description.
For example, when testing an A4 sized document, the media settings shall be set to A4, and when testing a
8.5”x11” size document, set to 8.5”x11”, and so forth. Verify the printing device and print driver default page
margin settings are not larger than 12,7 mm (0,5 inches). Adjust the settings as necessary to insure the test
page printable area is rendered correctly. Adjust the settings as necessary to insure the test pages printable
area is rendered to cover the paper page area as shown in the softcopy display of the test file. Any
modifications to the printing device or print driver settings shall be recorded. Page placement modifiers such
as page centering and auto-rotation can be used to place the image properly on the page. Any change from
the printing device defaults shall be recorded in the Full Detailed Report.
NOTE Adjust the settings such as turning off “page scaling” setting to ensure the test page printable area is rendered
correctly.
Output shall be collated. If collated output is not included in the default settings, follow the manufacturer’s
recommendation for obtaining collated output. In the case that collation settings do affect performance, the
faster of the results should be reported. As with other settings, the test report shall disclose the manner in
which collation was achieved.
For colour and B&W printing devices,
